Circuits Physlet-Based Curriculum

These examples of curricular material appear in Section 9.5. Follow a link on the left to go to the individual Physlet problems found in that section and several bonus problems only available on this CD. Below is a brief description of each animation.

Chapter Problems:

9.5.1: There are three unknown circuit elements connected to a voltage source as shown.  The voltage is controlled by the slider and given in Volts. 

9.5.2: An oscilloscope is connected to a sine ac supply voltage as shown above. By clicking in the graph window, you can read the voltage values.

9.5.3:  There is a resistor in a  circuit connected to a voltage source as shown.  The voltage is controlled by the slider and given in Volts. 
9.5.4: An unknown resistor is connected to an AC voltage source as shown.  The rms source voltage is controlled by the slider.  You can click-drag inside the graph to measure coordinates.   9.5.5: The circuit is an RC circuit with a capacitance of  0.30mF. The graph displays current vs. time. You may read values from the graph clicking the mouse anywhere on the graph    9.5.6: The circuit with a battery, an inductor and a 20 Ohm resistor can have a battery connected or disconnected depending on which switch is open. 
9.5.7: The circuit with an inductor and an initially charged 2mF capacitor, evolves in time. You may determine the current from the graph.  9.5.8: The circuit with an inductor, a 3.0 Ohm resistor, and an initially charged 4.8 mF capacitor, evolves in time. You may look at the charge on the capacitor from the graph.  9.5.9: An unknown circuit element is connected to an AC voltage source as shown. 
9.5.10: Find the resonant frequency of the LRC circuit.     

 

Additional Problems:

9.5.ap 1: An unknown resistor is connected to an AC voltage source as shown.  You may click in the graph window to read values for voltage and current.  9.5.ap 2: There is a resistor in a  circuit connected to a voltage source.  The voltage is controlled by the slider and given in Volts. You can measure the voltage and current by placing the mouse cursor over either meter or by looking at the graphs. 
9.5.ap 3: You are given two situations to evaluate, one involves only one battery and the other involves two batteries in series. All batteries are identical and have identical internal resistances.  9.5.ap 4: An unknown circuit element is connected to an AC voltage source as shown.  
9.5.ap 5: A light bulb is connect to two ideal batteries in three possible ways. Place the mouse on the various circuit elements to read their values. 9.5.ap 6: The circuit with a battery, an unknown inductor, and an unknown resistor evolves in time after the switch is closed.  The graph displays the current flowing from the battery after the switch is closed.
